Shandong water well drilling rig consisting mainly of: diesel engine, clutch, transmission, transfer case, drive shaft, pump, water pump, vacuum pump, rotary table, faucet, winches, hydraulic system, control, mast, drill, frame, and so on.

Shandong wells rig of work principle: Shandong wells rig of work way is pump sucking anti-cycle type, its work principle is: in atmosphere pressure of constantly role Xia, cycle liquid by precipitation pool by back ditch Hou, along wells of ring clearance has been flow to bottom, at turntable drive drill pipe led bit rotating for drilling, by pump pumping sucking Hou established of negative pressure, put debris and mud inhalation to drill pipe within cavity, then rose to taps, by pump row into precipitation pool, precipitation Hou of cycle liquid continues to into well hole, so cycle, Forming a reverse circulation drilling work.

1, hydraulic pumps: twin, large displacement pump to power power head, small-displacement pumps are classified into four Outrigger cylinder, mast oil tank, Afterburner/lifting pulley power cylinder.

2, four legs: small drilling devices fixed by hydraulic cylinder and frame. Body level can be adjusted at the work site, and play a role in supporting and stabilizing the body.

3, mast: for giant steel tube, steel and angle steel welding frame, powered with recessed channel on both sides first to run up and down the track and ensure the drill vertical. Drilling mast landing was done by hydraulic cylinders.

4, power: used gear reducer body, its low speed shaft has a big hole in the middle of a mandrel, mandrel head can be connected the device of concrete and rubber tubes, filled with concrete; mandrel out through the flange connected drill pipes, drill bits. High-speed shaft driven by high torque hydraulic motors.
